Plant Structure and Function Lab
Title: Plant Structure and Function Lab

Objectives:

After doing this lab, you should be able to:
• Identify the correct plant tissues from the corresponding slides.
• Identify the different structures of a flower.
• Describe the functions of each flower structure.
• Describe the functions of each plant tissue.
• Answer the Analysis and Conclusion questions using multiple sentences.

Materials:
• Flower
• Scissors
• Tape
• Tweezers
• Lab Report

Procedure:

Plant Tissues – Part 1
Review each image in your lab activity slide show. Identify the correct tissue or organ below based on each individual slide. Several of these choices may be use multiple times.

• phloem
• stoma
• xylem
• guard cells
• dermal
• ground
• vascular


Slide 1_____Slide 2_____Slide 3______Slide 4_____Slide 5
a. xylem___a. guard cells_a. vascular__a. vascular___a. vascular
b. phloem__b. stoma____b. dermal___b. ground____b. ground
____________________c. ground___c. dermal_____c. dermal
____________________d. dermal_______________________.

Flower Dissection - Part 2
• Pick a flower from your yard, a public location, or somewhere in your neighborhood.
• Start by removing the sepals of the flower with a tweezer. If you do not have a tweezer, a small pair of scissors will also work. It may be easiest to do this if you hold the flower with your finger from below the pedicel (small stalk just underneath the flower) and begin to remove the sepals with a pair of tweezers.
• Using tweezers, place the sepals on the labelled printable worksheet, and tape them in place.
• Repeat the same procedure for the petals and pistil.
• Remove all but one of the stamens and tape them onto the worksheet.
• On your printable worksheet, you should have sepals, petals, stamens and one pistil.
• Take a picture of your worksheet with the flower pieces placed correctly, and save it on your computer. You will attach and submit this with your assessment questions.

Analysis and Conclusion - Part 3

Plant Tissues:
1. What are three characteristics that all species belonging to the plant kingdom have in common?

2. How will the numbers of stomata differ in tropical plants and desert plants? How does this help protect the health of a plant?

3. If a plant's xylem and phloem become damaged, what type of damage will result within the plant? Describe the different roles on the xylem and phloem in your answer.

4. Why do we compare the dermal tissue of plants to human skin? Explain your answer.

5. Would a plant be able to survive if the ground tissue was damaged? Explain your answer.


Flowering Reproduction:
1. Describe how flowering plants reproduce.

2. How do flowers help other organisms in our environment?

3. Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.

4. Describe what occurs during the process of seed development.

5. Based on your knowledge of flowers, why do you think most flowers are bright in color?

The plant is made up of root and shoot structures that contain parts that enable the plant to grow and manufacture its food.

The structure and function of plants

The structure of plants is made up of tissues such as:

  • phloem
  • stoma
  • xylem
  • guard cells
  • dermal
  • ground and
  • vascular.

The three characteristics that all species being to the plant kingdom have in common are:

  • They are non-motile,

  • They make their food hence are called autographs; and

  • Their cell walls are made sturdy by a material called cellulose

The tropical plants have more stomata than the desert plants. This helps the desert plants to reduce water loss.

Some defects occur when there is damage to the vascular tissues such as the xylem( plant will not be able to transport water from the soil through roots to leaves) and phloem (nutrients produced during photosynthesis will not be able to reach every part of the plant body).

The dermal tissue of plants and the human skin performs protective roles to the underlying tissue organs.

A plant won't be able to survive because it won't absorb water and nutrients from the soil and transport it upwards to all the parts of the plant.

Flowering reproduction in plants takes place through the following steps:

  • Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination.
  • Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.

Flowers benefit other organisms in our environment by creating more carbon dioxide-absorbing and oxygen-radiating plants.

The flowers contain male reproductive organs called stamens and female reproductive organs called pistils.

The process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote.

Most flowers are bright in color because they are like advertisement signs for pollinators.
